The 30-year-old reality star is hoping to lose 15lbs before she says 'I do' to fiancé Kris Humphries later this year, and has enlisted celebrity trainers Gunnar Peterson and Tracy Anderson to help whip her body into shape.
Tracy told Life & Style magazine that she is working with the size-4 socialite to make sure that she keeps her famous curves.
'We don't want to take away Kim's amazing curves, so we just do specific movements to tighten the skin and to pull the muscles tight against the bone,' she explained.
